Thx Ross, I have a couple in light blue throughout, it does look quite a lot like a Per Lutken colourway. The only alternative pattern this vase could be is a Jan beranek design from the same time, but this would require three blobs sticking out of the vase near the base, which I cannot see from the picture. If these are not present, the shape and height makes a solid attribution for the Emanuel design previously mentioned, as suggested by Langhaugh too, it was made in two heights 22cm and 16cm, a nice piece,

I have a nice near contemporary Skrdlovice vase in exactly the same blue, they are very nice pieces and the single colourway makes them a bit unusual, I don't think it lasted for many years this light blue throughout look at Skrdlovice, very nice though!!

Glad that Robert has confirmed. Your version, Ross, is a good one. As you say, sinuous, where my piece drifts a little towards the clunky.

On my monitor there is some green in Robert's piece, which I'm presuming is only on my monitor. Emanuel must have liked the colour as my piece in that colour is also by Emanuel at around that time. I think it's a very striking, if subtle, colour, just a little softer than Lutken's light blue.
